COMPUTATIONAL FLUID DYNAMICS

COMPUTATIONAL FLUID DYNAMICS

INTRODUCTION:

Computational Fluid Dynamics (CFD) is predicting what will happen, quantitatively, when fluid flows, often with complications of: -
 Simultaneous flow of heat
 Mass transfer (e.g. perspiration, dissolution)
 Phase change (e.g. melting, freezing, boiling)
 Chemical reaction (e.g. combustion, rusting)
 Mechanical movement (e.g. of pistons, fans, rudders) by computer modeling.
The attraction of subject is twofold. Firstly, the desire to be able to model physical fluid phenomena that cannot be easily simulated or measured with a physical experiment, for example weather systems or hypersonic aerospace vehicles. Secondly, the desire to be able to investigate physical fluid systems more cost effectively and more rapidly than with experimental procedures.
Using CFD software you build virtual prototype of the system or device you wish to analyze. You then apply the real world physics to the model and software give precision data which predicts the performance of that design.
